Methodological critique can disprove a proof but never disprove a theory

Evidence

Hyman and Sheatsley (1954) summarize their masterful methodological critique by saying: “Our major criticisms lead us inevitably to conclude that the authors’ theory has not been proved by the data they cite…” (p. 119). Notice the care with which this conclusion is formulated: the theory has not been proved by a particular set of data. A methodological critique cannot conclude that a theory is mistaken. — John T. Jost and Jim Sidanius, Political Psychology, 642
